quheatmap {QUBIC}R Documentation

Visualization of identified biclusters

Description

This function can visualize the identifed biclusters using heatmap in support of overall expression pattern analysis,either for a single bicluster or two biclusters.

Usage

quheatmap(x, bicResult, number = 1, showlabel = FALSE, col = c("#313695",
  "#4575B4", "#74ADD1", "#ABD9E9", "#E0F3F8", "#FFFFBF", "#FEE090", "#FDAE61",
  "#F46D43", "#D73027", "#A50026"), ...)

Arguments

x

The data matrix

bicResult

biclust::BiclustResult object

number

which bicluster to be plotted

showlabel

If TRUE, show the xlabel and ylabel

col

default: c("#313695", "#4575B4", "#74ADD1", "#ABD9E9", "#E0F3F8", "#FFFFBF", "#FEE090", "#FDAE61", "#F46D43", "#D73027", "#A50026")

Examples

# Load microarray matrix
data(BicatYeast)
res <- biclust::biclust(BicatYeast, method=BCQU(), verbose = FALSE)
# Draw heatmap for the 2th identified bicluster
par(mar = c(5, 4, 3, 5) + 0.1, mgp = c(0, 1, 0), cex.lab = 1.1, cex.axis = 0.5, cex.main = 1.1)
quheatmap(x = BicatYeast, res, number = 2, showlabel = TRUE)
# Draw heatmap for the 2th and 3th identified biclusters.
par(mar = c(5, 5, 5, 5), cex.lab = 1.1, cex.axis = 0.5, cex.main = 1.1)
quheatmap(x = BicatYeast, res, number = c(2, 3), showlabel = TRUE)
